Value Collection 40860 Button Cap Screw 6-32 5/8 in 50-pack

Product Description

The VALUE COLLECTION 40860 is a 6-32 button socket cap screw designed for applications requiring a low-profile fastener head with reliable clamping force. Driven by a 5/64-inch hex socket, this screw is fully threaded along its 5/8-inch length under head. The alloy steel construction with black oxide finish provides corrosion resistance and a hardness rating of 36-43 HRC, making it suitable for moderate-duty mechanical assemblies. Sold in a package of 50, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. Licensed tradespeople and assembly technicians working in industrial, mechanical, and OEM fabrication environments will find this a reliable stock fastener.

This button socket cap screw is suited for use in machine assemblies, panel mounting, enclosures, and component fixturing where a flush or low-profile head is required. The UNC thread form and right-hand thread direction make it compatible with standard tapped holes and threaded inserts in steel, aluminum, and similar base materials. The black oxide finish reduces light reflection, which is useful in optical, electronic, and precision mechanical assemblies. Each package contains 50 pieces, suitable for production-volume or repeat-service applications.

Key Features

• Fully threaded 5/8-inch length under head with 6-32 UNC thread form
• Hex socket drive requiring a 5/64-inch driver for precise torque application
• Button head profile minimizes protrusion above the fastened surface
• Alloy steel construction with 36-43 HRC hardness for reliable clamping strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC replacement or stock fastener for mechanical assemblies, enclosures, or fixtures requiring a 6-32 button socket cap screw with a hex socket drive.

Installation Notes

Installation is performed with a 5/64-inch hex key or hex socket driver. Ensure the mating tapped hole or threaded insert conforms to a 6-32 UNC Class 3A thread fit specification before installation. Do not exceed the design torque range for alloy steel 6-32 fasteners, and inspect the drive recess for debris before seating the driver to avoid cam-out damage. Follow applicable ANSI or equipment-specific torque guidelines for the assembly.
